This bracket is preferably constructed of channel iron, as shown, and the pole 'f is cut short so as to produce in effect a stub lpole as compared with a full length pole commonly used when the mower is horse drawn. On its lower part the lower arm of the supporting bracket is provided 'with izer.v

I Thenumeral represents a longitudinal.y draw bar which is preferably constructed of iron `and has its front and rear ends offset vertically relatively to each other, the

depressed front end 26 passingthrough the guide opening 24 of the supporting bracket and the .elevated rear end'27 'of the same yrear end engages with theitop of the web 18y and is connected with the same and the Vrear end 27 of thedr'aw ba-r'by means of a vertical coupling pin 30, as shown in Fig- Upon pulling forwardly on the' draw'bar fthe frame or lcarriage of ythe mower is moved forwardlyas well as the shoe and cutter-bar and other parts associated there- `rwith Ywhich pull of the draw bar is transymitted to these A'parts with an equalizing effectthrough the medium of the equalizer referred to. The draw bar is alsocapable p of movingbackwardlyrelatively to the supporting bracket, pole, cutter bai and asf sociated parts, but this backward movement the mower.

ofthe draw bar is limited so that th'e'power of the ,tractor mayA be utilized to baclc'up For this purpose a stop is mounted ony the draw bar for engagement with the front side of the lower arm ofthe supporting' bracket which stop may be of various forms, but preferably consists of a bolt 31 secured to the front part of the draw bail and engaged with its head with the front side of `the` supporting bracket. s

By'means of this portion of the hitching mechanism a pulling' effect is produced upon the 'carriage' and cutter bar of the mower which is identical with t-he pulling effectheretofore produced by animal power, such f asa horse hitched tothe pole-,and to the s equalizer in the manner heretofore l commonly practiced, and the carriage and cutter' bar are also guided over the field which is to be 'mowed The mower is also capable ofbei 'ing "backed up in the present case by the power tractor with" substantially the same eifect as has been done heretofore by animal .A i power.,I Y

Means are provided for connecting the front end of the draw bar of the 'hitching mechanism wit-h the rear end of the pulling yand lower draw plates 32 and 33 of metal'. Y the rear ends of which receive between' them the front end 36 of the draw bar and are detachably connected therewithby means of a bolt 34 `while the front ends of the same receive between them the pull member 20 of the tract-o1' and are detachably connectedV therewith by means of a plurality of fastening vbolts 35. Between the centralpart of the draw plates 32 and 33, is arranged fa spacer 36 which maintains these plates vin L spaced relation and which is secured to vthese Vplates by means of fasteningbolts 37, as

shown in Figures 5 and 6. The drawplates are preferably cut at an angle so that they incline laterally from the tractor which is running on the stubbleward part ofthe Held rearwardly toward the mower which is run- ,ning` on the' grainward part of the field. The front ends of the draw plates are preferably rigidly secured to the pull' member' of the tractor by means of the bolts 35 andthe rear ends of these plates are provided with openings 38`which are arranged. in a transverse row so that the coupling bolt 34 may Abe shifted from one pair of corresponding openings 38 in the draw plates to another and thereby bring the line of draft of the tractor relative to the line of draft of theY mower into different positions relatively' to each other. By this means it is possible to adjust the connection between the tractor and the mower so as to 'produce the desired pull upon the latter and 'stillv enable the mower toy run with its critter bar over the uncut part of the field while the tractor is running wholly over the cut portion of the field.

If desired the oblique coupling means may be dispensed with and instead the front end 26 of the draw bar may be connectedV by a bolt 39 directly with the pulling member 201 at the rear end of a' tractor,'as shown in Figures 7 and 8.

The means whereby this lateral vadjustment of the tractor and mower relatively to each other is effected are 'comparatively simple in construction, Vthey are not 'liable to get out of order and it ispossibleto effect the adjustment of the tractor and'mower rel-` atively to each other with ease and facility. I claim as my invention VA'The combination witha mower 'having a pole, a cutter bar, a shoe supporting the cutter bar and an upright equalizing bar pivoted at its upper end to said pole and connected at. its lower lend with said bar,` of means for bitching said mower to a tractor comprising a bracket mounted on-said pole,
